ABSTRACT:
A computer-controlled machine tool includes force deflection and tool-part contact sensors. A tool is inserted in the chuck of the automatic machine tool and the tool is driven over a deflection testing pad on the work support so that upon contact a first tool deflection force is measured. Then the tool is driven a small increment in the same direction to provide a second but greater tool deflection force in the same direction. Then the computer calculates the differential value of the tool deflection force over the distance moved. Also the error between estimated and actual tool diameter is calculated from the difference between the tool offset value used and the distance required for adjustment of the tool from a spaced starting position to contact with the pad.
